But until that version of the adaptation of P.L. Travers' beloved magical nanny series arrives, we're just fine with ... James Corden?

Well, sure we are! Because it's James Corden!

Julie Andrews and James Corden as Mary Poppins ... in near-identical outfits!

Corden is in London, filming a batch of shows that will air starting the week of June 5, and photographers caught a glimpse of one of his most hilarious routines, "Crosswalk the Musical," being enacted on the streets there.

In any case, it's yet another chance for Corden to belt out the big numbers while strapped into multiple dresses as one of his guests is dragged into the performance, like it or not. This time around it's Oscar-winning actor Ben Kingsley who's taking on the role of Bert, and he appears to have had a rollicking good time.

In fact, the whole thing seemed just supercalifragilisticexpialidocious!

Take a bow, James! Er, Mary!

Roses for an English rose.

We'll have to wait until next week to see the finished production, but we're already setting our DVRs to record. This one is making us truly chim-chim-cheery!
